From an article in the ValleyTimes today:
"Residents reported to police that they saw a man in a red minivan taking mail from boxes on MacDonald Court and Moller Ranch Drive. A Pleasanton motorcycle officer, who was on Moller Ranch, saw the vehicle, stopped it, and detained the three men inside.
Inside the van, officers found mail and checks stolen from Pleasanton, Livermore, Castro Valley, Clayton and Concord. They also found chemicals used to wash the checks of ink.
Police believe the men were taking the checks and forging them."
